I do know how to change user passwords. That is not at issue. Rather, I do not want my password and username to display in the DietPi banner on boot. This information It shows at the bottom of the banner and just above the shebang on boot up. My query is about how to stop that default behavior.

I will try to capture the boot screen with the undesired information partially redacted as evidence of the problem.

I think that what Fourdee is saying is that your password and username are NOT shown in the boot up process.

What it is shown in the boot up process are the DEFAULT username and password, the same information that could be found on Google. Which I did not notice but I think it is a great idea, so you don't have to Google that if you are as impatient as I am.

Thanks for sharing, jep that is possible but reverted with dietpi-update.

We could change it a way that this is only printed on first login prompt. Afterwards users are anyway asked to change their password and they will know how to login then, what you think?

And for security concerns mentioned before, indeed its only the default password, that you are asked to change during firstrun setup, not the actual password that you applied . But indeed this is only useful for the very first login.
